Carbotech pads are the bomb and they're very expensive.
Carbotech - Racing
They are a complete waste for a street only driven car or even autox. If you take your car to road courses though they are the best option out there I've found. Only time I've ever felt a Carobotech XP-8 fade a *little* was when it was just about down to the backing plate. If you want phenomenal braking they are the ****.
